Abstract (en)
The water stop device comprises a solenoid valve having a body (10), an inlet pipe (12) and an outlet pipe (14), a flexible inner water flow tube (16) and a flexible outer safety tube (20) arranged around the inner tube (16), so as to define an annular air gap (22). Both the inner tube (16) and the outer tube (20) arc of corrugated type. The proximal end (18) of the inner tube (16) faces the distal end (26) of the outlet pipe (14) in such a way that the respective longitudinal axes (24) coincide, and the ends (18, 26) can be associated with one another by means of a tubular sleeve (28) arranged, sealed, coaxially on their exterior. Advantageously, the sleeve (28) is made of polymeric material and is produced by a co-moulding technique.
